ANTIPOLLUTION CARBURETOR ATTACHMENT BACKGROUND OF THE INVENTION Field ofthe Invention The present invention relates to the reduction of noxiousair pollutants emitted by an internal combustion engine by feeding watervapors into the exhaust system or into the air intake of the carburetorwhile the engine is in operation.

SUMMARY OF THE INVENTION The present invention is directed to airpollution reducing attachment for the carburetor of internal combustionengines. Water vapors are drawn from a source of warm water such as aradiator of a car or auxiliary heated water tanks and fed into the airintake of the carburetor through the conduit which holds the PVC valveor are fed direct to the exhaust pipe of the engine. Moisture when fedinto the carburetor substantially reduces the carbon monoxide gasesemitted by the engine while simultaneously improving the gas mileage andcausing the engine to run quieter.

The primary object of the invention is to provide an antipollutionattachment for carburetors or exhaust systems of internal combustionengines which will reduce the carbon monoxide pollutants from theengine.

Other objects and advantages will become apparent in the followingspecification when considered in light of the attached drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now to the drawings indetail wherein like reference characters indicate like parts throughoutthe several figures the reference numeral 10 indicates generally anantipollution attachment for carburetors constructed in accordance withthe invention.

The attachment 10 is connected to a conventional radiator 11 having atop tank 12 through which a copper tube 13 extends. The copper tube 13has a projection 14 at one end which is soldered at 15 to the end of thetop tank 12. A projection 16 is formed on the copper tube 13 at the endthereof opposite the projection 14 and this is soldered at 17 to the endof the top tank 12. The copper tube 13 has perforations 18 formed in itsupper face within the top tank 12.

An air inlet elbow 19 is secured to the projection 14 and has its openend 20 projecting downwardly. A Y-fitting 21 is secured to theprojection 16 and has a hand control shutoff valve 22 secured to onebranch and a similar valve 22v secured to the opposite branch. A conduit23 extends from the valve 22 to the conduit 24 forming part of the airintake 25 of the air cleaner 26. The air cleaner 26 is associated withthe conventional carburetor 27 and the conduit 24 extends upwardly froma PVC valve 28 of conventional construction. A conduit 23c extends fromthe valve 22v directly to the exhaust pipe E of the engine.

When the valve 22 is open with the valve 22v closed and the internalcombustion engine is in operation air will flow through the air inlet 20then flow with water vapors through the perforations 18 into the coppertube 13 where they will flow into the conduit 24 and then into thecarburetor 27 to provide the desired moisture containing air to reducethe carbon monoxide gases formed in the operation of the internalcombustion engine. It has been found that the internal combustion enginewill give better gas mileage after the installation of this device andwill operate quieter.

In FIGS. 3 and 4 a modified form of the invention is illustrated whereina tank 31 mounted adjacent the internal combustion engine and has anexhaust pipe 32 extending through the tank 31 in a zigzag path exitingat the bottom thereof. A filler pipe 33 extends into the tank 31 inorder for it to be filled with water. An air inlet pipe 34 is connectedto the tank 31 to permit air to flow into the top of the tank asrequired.

A Y-fitting 35 extends from the upper portion of the tank 31 and has ahand-controlled valve 36 connected to one branch thereof and a valve 36vconnected to the opposite branch thereof permitting the branches to beindividually closed off when desired. A pipe 37 extends from the valve36 to the carburetor (not shown) in the same manner as the preferredform of the invention and a pipe 370 extends from the valve 36v directlyto the exhaust pipe E of the engine.

In the modified form of the invention illustrated in FIGS. 3 and 4 atleast a portion of the exhaust gases are diverted through the exhaustpipe 32 to heat the water in the tank 31 so that water vapors will bepresent in the upper end of the tank 31. The operation of the form ofthe invention illustrated in FIGS. 3 and 4 is identical to the operationof the preferred form of the invention.

In FIGS. 5 and 6 another modified form of the invention is illustratedwherein a water tank 41 surrounds a conventional muffler 42 which isconnected to an exhaust pipe 44 and to a tailpipe 45 in a conventionalmanner. A filler pipe 46 is connected to the tank 41 to permit water tobe poured into the tank 41. An air inlet pipe 47 is connected to thetank 41 to pennit a flow of air to enter the tank 41. A Y-fitting 48 isconnected to the tank 41 and has a hand-controlled valve 49 connected toone branch thereof and a valve 49v connected to the other branch. A pipe50 extends from the hand control valve 49 to a carburetor (not shown) inthe same manner as disclosed in the preferred form of the invention inFIG. 1. A pipe 50c extends from the valve 49v to the exhaust pipe E.

The operation of the form of the invention illustrated in FIGS. 5 and 6is identical to that of the form of the invention illustrated in FIG. 3with the muffler 42 heating the water in the tank 41 to provide thedesired water vapors.

In FIGS. 7 and 8 still another modified form of the invention isillustrated wherein a water tank 51 has the exhaust pipe 52 extendingtherethrough on its way to a muffler 53. A filler pipe 54 is providedforpouring water into the tank 51 and an air inlet pipe 55 is connected tothe tank 51 and an air inlet pipe 55 is connected to the tank 51 topermit a flow of air into the tank 51 as required. The water vaporY-fitting 56 is connected to the tank 51 and has one branch whichextends to a valve 57 controlled by hand and a second branch extendingto a valve 57v. A pipe 58 leads from the hand control valve 57 to thecarburetor (not shown) in exactly the same manner as illustrated in thepreferred form of the invention in FIG. 1. A pipe 58c extends from thevalve 57v to the exhaust pipe E. The tank 51 has a central cylindricalpipe 59 extending therethrough with the exhaust pipe 52 arrangedcoaxially therein but inwardly spaced therefrom.

The operation of the form of the invention illustrated in FIGS. 7 and 8is identical to that of the form of the invention illustrated in FIG. 3with the water in the tank 51 being heated by the exhaust gases in theexhaust pipe 52.

Having thus described the preferred embodiments of the invention itshould be understood that numerous structural modifications andadaptations in addition to those illustrated may be resorted to withoutdeparting from the spirit of the invention.
